Shopify Plus B2B wholesale checkout and ERP line sync
Volume pricing, PO numbers, and Netstock inventory loops, custom checkout UI and webhook reconciliation.
By Simplileap · Published November 28, 2025 · 9 min read
A home goods wholesaler migrated from Magento to Shopify Plus, 2,400 B2B accounts, tiered pricing, MOQ rules, and Netstock ERP inventory. Buyers expected PO number capture and net-30 invoicing outside standard Shopify consumer checkout.
Implementation: Shopify B2B company profiles; Checkout UI extensions for PO and delivery window; custom app proxy for credit limit check against ERP; webhook-driven order export with retry and idempotency.
Problems: Checkout extensibility API limits required splitting validation client-side and server-side; legacy Magento URLs, 4,100 redirect rules; some SKUs dual-UOM, line item properties mapped in export transformer.
Performance: Hydrogen not in scope, Liquid theme optimized with selective JS defer; Core Web Vitals monitoring on catalog templates.
Outcome: B2B order error rate 6% → 0.4%; ERP sync lag under five minutes p95; Black Friday week without manual order re-entry. Wholesaler identity withheld.
